(Cl. 206-65) ABSTRACTOF THE DISCLOSURE Packages of the class having two end cap membersoverlying the ends of a row of articles, the two outer articles havinghollow end portions and the cap members having bottom wall panels fromwhich extend two tongue-s at the ends thereof which interfit with thehollow end portions of the two outer articles.

Background of the invention This invention relates generally topackaging, and relates specifically to a package for a row of two ormore articles in which at least the two outer articles have hollow endportions. This invention is particularly useful in the packaging oftubular articles made from a flexible or structurally weak material,such as rolls of paper.

The typical prior art package for a row of two or more articles in whichthe outer articles have hollow end portions involves placing a cardboardcap over the ends of the articles. Such a cap is usually an ordinary boxopen along one side to fit over the ends of the articles. Generally, anoverwrap of flexible packaging material is applied around the entireassembly. A prior art package of this type is often used to package, forexample, rolls of paper, such as wrapping paper, which are wound intofairly long rolls and form a flexible or relatively structurally weakarticle. When packaged according to the prior art, it has been foundthat it is usually necessary to provide a reinforcing core for each rollin the row of articles in order to give a package which has adequatestrength.

Summary of the invention This invention provides a solution to theproblem of prior art packages heretofore mentioned which enables one todispense with the usual reinforcing cores for the articles situatedintermediate the two outer articles in the row, and still provides asufficiently strong package. This is accomplished by a package whichincludes cap members for overlying the ends of the articles aligned in arow. These caps have a pair of special tongues which fit into the hollowend portions or reinforcing cores of the two outer articles in the row,so that in effect a frame of adequate strength is developed. Thus, thearticles intermediate the two outer articles in the row will no longerrequire reinforcing cores, for they are pro tected by a frame comprisingthe end cap members and the reinforcing cores of the two outer articles.

Some of the objects of this invention are to provide an improved packagefor a row of articles having hollow end portions in which the packageincludes cap members having tongues that engage the hollow end portionsof at least the two outer articles in the row; to provide a package ofparticular utility for packaging articles of flexible or structurallyweak material which will elimi-- nate the use of reinforcing cores onall of the articles; and to provide the particular carton or packageconstructions hereinafter described and claimed.

Description of the preferred embodiments Referring to FIGS. 1 to 4inclusive, the construction of a package embodying the invention in oneof the preferred forms will now be described. In FIG. 1 there is shown aflat blank 21 that is cut and scored to include panels, tabs and othermembers which define a cap member for overlying the ends of a row oftubular articles in accordance with this invention. In the constructionshown the cap member includes a first side wall panel 22, a first bottomwall panel forming member 23, a second bottom wall panel forming member24, and a second side wall panel 25. First side wall panel 22 and firstbottom wall panel forming member 23 are hinged together along fold line26, and the second "bottom wall panel forming member 24 and second sidewall panel 25 are hingedly connected along fold line 27, fold lines 26and 27 being parallel.

A pair of tabs 28 and 29 are hingedly connected to opposite ends of thefirst side wall panel 22 along spaced parallel fold lines 30 and 31,respectively, which lines are at right angles to parallel fold lines 26and 27 connecting the side wall panels and the bottom wall panel formingmembers. Parallel cuts 32 and 33 are formed in tabs 3 28 and 29,respectively, said cuts being at right angles to fold line 26.

Another pair of tabs 34 and 35 are connected to opposite ends of thesecond side wall panel along spaced parallel fold lines 36 and 37,respectively, said fold lines being at right angles to fold line 27. Thetabs 34 and contain parallel cuts 38 and 39, respectively, which cutsare at right angles to fold line 27 and aligned with cuts 32 and 33,respectively, in such manner that the tabs 28 and 34- and tabs 29 and 35will interlock to form a lockend type of closure when the cap member isfully assembled.

A first tongue 40 and second tongue 41 extend from and foldably connectthe bottom wall panel forming members 23 and 24 at the opposite endsthereof and serve to keep said members in a spaced apart relationshipwhile defining a rectangular space between said members when the capmember is in the form of an unassembled flat blank.

The first tongue 40 is composed of a first tongue forming member 42 anda second tongue forming member 43, foldably connected in series byspaced parallel fold lines 44, 45 and 46 to the first bottom wall panelforming member 23, to each other, and to the second bottom wall panelforming member 24, respectively. The second tongue 41 is composed of afirst tongue forming member 47 and a second tongue forming member 48,foldably connected in series by spaced parallel fold lines 49, 50 and 51to the first bottom wall panel forming member 23, to each other, and tothe second bottom wall panel forming member 24, respectively. The foldlines 44, 45, 46 and 49, 50, 51 are aligned with each other and areparallel to fold lines 26 and 27. Parallel cuts 52 extend at rightangles from the interior end of each parallel fold line 44, 46, 49 and51 toward the rectangular space between the bottom wall panel formingmembers and terminate thereat.

The cuts are herein shown in solid lines to denote that they extendentirely through the thickness of the sheet material, but they can alsobe formed by perforated lines. The fold lines are shown as dash lines toindicate that they do not extend through the sheet material but arecreased portions of the sheet material and serve as hinges for folding.The various cuts and liold lines can be formed by means or devicesgenerally used in the manufacture of foldable cartons, for example, thecut lines may be formed by die-cutting through the sheet material andthe fold lines can be formed by scoring the sheet material so that itwill bend easily about the scored portions. The sheet material is bestmade of foldable material of the type commonly used in the manufactureof cartons such as paperboard, cardboard, or any other similar material,although plastic materials, particularly the self-hinging syntheticplastics, also may be utilized in its construction.

FIG. 2 shows the erected or assembled blank illustrated in FIG. 1. Thefirst side wall panel 22 is folded at a right angle to the first bottomwall panel forming member 23 along fold line 26. The second side wallpanel 25 is folded at a right angle to the second bottom wall panelforming member 24 along fold line 27. The second bottom wall panelforming member 24 is brought into overlapping position with respect tothe first bottom wall panel forming member 23, the leading edge thereofabutting the first side wall panel 22 along fold line 26. Thisoverlapping arrangement of the bottom wall panel forming members 23 and24 results in the formation of a bottom wall panel which is reinforced.Moving the bottom wall panel forming members 23 and 24 into overlappingposition also results in the erection of tongues 40 and 41 which, as canbe seen, are in position to receive and interfit with the hollow endportions of the two outer articles in the row to be packaged. Tabs 29and 35 are folded along their respective fold lines 31 and 37 at one endf the side Wall panels 22 and 25, respectively, and interlocked by meansof the cuts provided, in etfect providing the cap member 53 with an endwall.

Turning now to FIG. 3, a row of five tubular articles 54 is shownpackaged in accordance with the invention. Cap members 53 overlie theends of the tubular articles aligned in a row. Bottom wall panel 55 isformed from the bottom wall panel forming members 23 and 24 heretoforedescribed. The bottom wall panels 55 have a first side edge 56 fromwhich extends the first side wall panel 22. A typical finished packageas shown in FIG. 3 can be encased by a sheet 57 of flexible packagingmaterial (usually transparent) which is wrapped around the assembly ofthe end cap members 53 and the row of tubular articles 54, but it is notnecessary. It is preferred that any wrapping snugly engages the outersurfaces or outline of the assembly thus formed. Examples of suitablematerials for the sheet 57 are cellophane, polyethylene coatedcellophane, polyethylene coated polyester film, polyethylene film,vinylidene chloride polymer film and wrapping paper.

As indicated in FIG. 4, the tongues 40 and 41 which extend in adirection normal to the plane of the bottom wall panel engage orinterfit with the reinforcing cores 58 of the two outer tubular articlesin the row. This form of construction in the package serves to providerigid support for the entire assembly without the necessity of thearticles intermediate the two outer articles in the row havingreinforcing cores at additional expense. In effect, a rigid frame isformed comprising the two end cap members 53 and the reinforcing cores58 of the two outer tubular articles.

FIGS. 5-6 illustrate another form in which some of the principalfeatures of the present invention may be embodied. A fiat blank 21a isshown which illustrates another form of the cap member shown in FIG. 1.The major difference is the arcuate or U-shaped cuts 60, 61, 62 and 6-3in tabs 28, 29, 34 and 35, respectively, to obtain a. different type oflock-end closure. The cuts 60, 61, 62 and 63 are positioned such thattabs 28 and 34 and tabs 29 and 35 will interlock when the cap member 53ais assembled. Alternatively, instead of the lock-end type of closuremeans illustrated in FIGS. 1-6, a seal-end type of closure means can beused wherein the tabs are glued or otherwise adhesively held together.

FIGS. 7-10 illustrate still another form in which some of the principalfeatures of the present invention may be embodied. A flat rectangularblank 21b is shown as including cuts and score lines at one end thereofto define a first cap member 53b. In the construction shown this firstcap member includes a first side wall panel 22, a first bottom wallpanel forming member 23, a second bottom wall panel forming member 24,and a second side wall panel 25a which is shared commonly with a secondcap member 53b at the opposite end of the blank 21b to be describedbelow. First side wall panel 22 and first bottom wall panel formingmember 23 are hinged together along fold line 26, and the second bottomwall panel forming member 24 and second side Wall panel 25a are hingedlyconnected along fold line 27, fold lines 26 and 27 being parallel.

A first tongue 40 and second tongue 41 extend from and foldably connectthe bottom wall panel forming members 23 and 24 at the opposite endsthereof and serve to keep said members in a spaced apart relationshipwhile defining a rectangular space between said members when the capmember is in the form of an unassembled flat blank.

The first tongue 40 is composed of a first tongue forming member 42 anda second tongue forming member 43, foldably connected in series byspaced parallel fold lines 44, 45 and 46 to the first bottom wall panelforming member 23, to each other, and to the second bottom wall panelforming member 24, respectively. The second tongue 41 is composed of afirst tongue forming member 47 and a second tongue forming member 48,foldably connected in series by spaced parallel fold lines 49, 50 and 51to the first bottom wall panel forming member 23, to each other, and tothe second bottom wall panel fonming member 24, respectively. The foldlines 44, 45, and 46 and 49, 50, 51 are aligned with each other and areparallel to fold lines 26 and 27. Parallel cuts 52 extend at rightangles from the interior end of each parallel fold line 44, 46, 49 and51 toward the rectangular space between the bottom wall panel formingmembers and terminate thereat.

The blank 21b is shown as including cuts and score lines at the oppositeend thereof which define a second cap member 53b. The detaileddescription of the second cap member 53b is identical to that givenheretofore for the first cap member 53b except for designatingcorresponding parts thereof with the sufiix a.

In addition to the second side wall panel 25a being shared commonly bythe cap members 53b at both ends of the package serving to join them andto define a package in tray-like form, this particular embodimentcontains no end closure means, e.-g., locking tabs or glue tabs,although it can contain such closure means as is described and shown inFIGS. 1-6 heretofore. A typical finished package is shown in FIG. 9,wherein a sheet 57 of flexible packaging material (iusually transparent)encases the tray and the row of tubular articles 54 contained therein.The sheet 57 is preferably used with this embodiment as illustrated toprovide support in view of the fact that the end cap members 53b have noseal-end or lock-end closure means. FIG. shows the tongues 40 and 41engaging or interfitting with the reinforcing cores 58 of the two outertubular articles 54 in the row. Again, the interior tubular articlesrequire no reinforcing cores.

In a further modification of the package illustrated in FIGS. 71(), asecond side wall panel a common to both end cap members 53b need not beemployed. Each end cap member 53b can use its own independent secondside wall panel such as described in FIGS. l-6 heretofore.

FIGS. 11-13 illustrate a further form in which some of the principalfeatures of the present invention may be embodied. A portion of a fiatblank 210 is shown as including a pair of tabs 28a and 29a hingedlyconnected to opposite ends of the first side wall panel 22 and extendingto but no further than the edge of the fiat blank 210. The respectiveparallel fold lines 30 and 31 of the tabs, in addition to being at rightangles to fold line 26 connecting the bottom wall panel forming member23 and the first side wall panel 22, are generally aligned with theinterior edges of the first and second tongue forming members 42 and 47,respectively. Cuts 64 are at right angles to fold lines 30 and 31 aswell as being parallel to and aligned with fold line 26.

FIGS. 12 and 13 show the tabs 28a and 29a in unassermbled and assembledpositions, respectively, with the end cap member 530. The tabs 28a and29a are folded at right angles with respect to the first side wall panel22 along fold lines 30 and 31 respectively inwardly toward the secondside wall panel 25a. The ends of the tabs extend to and abut against thesecond side wall panel 25a functioning as a reinforcing element and as aseparator between the outer and intermediate articles in the row to bepackaged. In this case as in the previously described embodiment, acommon second side wall panel 25a is not an essential part of thepackage. If desired, an independent second side wall panel can be usedfor each cap member 530.

FIGS. 14-17 illustrate a still further form in which some of theprincipal features of the present invention may be embodied. A fiatblank 65 is shown as including a substantially different arrangement ofcuts and fold lines which serve to define another form of an end capmember 53d suitable for use in accordance with the present invention. Afirst side wall panel 22, a bottom wall panel 66, and a second side wallpanel 25b are connected in series by spaced parallel fold l-ines 26b and27b. A first tongue 67 and a second tongue 68 are each hingedlyconnected to opposite ends of the bottom wall panel 66 along parallelfold lines 69. Each tongue is composed of a first tongue forming member70 and a second tongue forming member 71 which are connected alongparallel fold lines 72, said lines being parallel to fold line 69.Arcuate members 74 are hingedly connected along parallel fold lines 73to the opposite free edges of the second tongue forming members 71. Thefold lines 73 are parallel to fold lines 72 and 69 Hingedly connected toopposite ends of the first side wall panel 22 along parallel fold lines75 are the first end walls 76. Hingedly connected thereto along parallelfold lines 77 are U-shaped tabs 78.

Cuts 79 extend at right angles from fold line 75 in alignment with foldline 26b and serve to separate the end walls 76 and tabs 78 from thetongues 67 and 68- and bottom wall panel 66.

Second end wall panels 81 are hingedly connected to second side wallpanel 25b along parallel fold lines 80. Hingedly connected to the secondend wall panels 81 along parallel fold lines 82 are reinforcing tabs 83.Cuts 84 extend at right angles from fold lines in alignment with foldline 27b and serve to separate the bottom wall panel 66, and the firstand second tongue forming members 70 and 71 from the second end wallpanels 81 and reinforcing tabs 83.

The second side wall panel 25b has a pair of parallel cuts 85 positionedparallel to fold lines 80 in such manner as to receive the U-shaped tabs78 for the purpose of forming a lock-end type of closure.

FIG. 15 shows the erected cap member 53d with the first and secondtongues 67 and 68 in a position perpendicular to the plane of the bottomwall panel 66, and having their transverse axes perpendicular to thelongitudinal axis of the bottom wall panel. The position of the tonguesin this embodiment differs from the position of the tongues in thepreviously described embodiments only in the fact that the transverseaxes of the tongues previously described were parallel to thelongitudinal axis of the bottom wall panel rather than perpendicularthereto.

As illustrated in FIG. 16, cap members 53d overlie the ends of a row oftubular articles 54. The first side edge 56 of the bottom wall panel 66connects the first side wall panel 22 with the bottom wall panel. Atypical finished package as shown in FIG. 16 preferably is encased in asheet 57 of flexible packaging material (usually trans parent).

FIG. 17 shows the first and second tongues 67 and 68, respectively,interfitting with the reinforcing cores 58 of the two outer tubulararticles 54. The first and second end walls 76 and 81, respectively,overlap and reinforce each other when the cap member is assembled andserve to separate the outer tubular articles in the row from the tubulararticles intermediate thereof.

It is contemplated that at least the two outer articles in the row oftwo or more to be packaged according to this invention will have hollowend portions. In at least the two outer articles the hollow end portionscan contain reinforcing cores into which the tongues of the end capmembers will be inserted. The reinforcing cores can either be full coresor stub cores.

Conclusion There has thus been described several presently-preferredembodiments of this invention each comprising a package for use with twoor more aligned articles in which at least the two outer articles havehollow end portions, the package being formed of opposed cap memberseach having a bottom wall panel extending over the ends of the articlesand tongues which are foldable to a position normal to the plane of thebottom panel to interfit with the hollow end portions of the two outerarticles. This structural feature provides an interengagement betweenthe cap members and the packaged articles to form a relatively rigidpackage that is useful for the packaging of articles of flexible orstructurally weak material, such as rolls of paper. The term hollow endportions as used herein in reference to the package articles is intendedto encompass articles which have a full core that extends entirelythrough the article from one end to the other and also articles having aso called stub core comprising a hort core at each end of the article.In the first four embodiments, the tongues are shown as being defined bytongue-forming panels connected to sides of the bottom wall and adaptedto be folded to an upright position in which one tongue forming panel issuperposed over the other, and in the fifth embodiment, the tongues areformed as panels connected to opposite end of the bottom wall. Variousforms of locking panel constructions are shown to aid in holding the endcaps in their desired erected condition. The invention is illustrated inthe form of a pair of separate but identical end caps and also in theform of a tray having one long side panel extending the length of thepackaged articles with an end cap construction of the specified typedefined along each end of the long side wall panel.
